What is the method for providing a starting value for a text field?

edit

The method for providing a starting value for a text field depends on the programming language or framework being used. In HTML, the "value" attribute can be added to the input tag like this:

<input type="text" name="username" value="JohnDoe">

In JavaScript or jQuery, the value can be set using the ".val()" method:

$("input[name='username']").val("JohnDoe");

In AngularJS, the initial value can be set using ng-init:

<input type="text" name="username" ng-init="username = 'JohnDoe'" ng-model="username">
